jailkit + chroot cron not working

To recreate the problem:
1. create a site
2. add a chroot cron job to that site

In the auth.log see error:
Jul 24 16:31:40 web2 jk_chrootsh[32617]: abort, path /var/www/clients/client15/web30/./home/web30 does not have group owner 1012, set option 'relax_home_group' to relax this check
